They'll must likely shrivel up outside, and if smell is an issue, there are various things you can do to combat that problem. DIY charcoal filters are cheap and easy and will clean the air running out of a vent. Just make sure to get a proper light, a 100-200w HID, either HPS or MH will do nicely, although the red light thrown off by HPS's is nice for flowering. Bringing them inside and giving them light from a regular incandescent bulb would be worse than leaving them to the elements.
